Limitation
The following are limitations for VISCA over IP as
compared with the VISCA specifications.
Locking the peripheral device's address of the
VISCA message to 1
VISCA over IP cannot reflect each address to the
address of the VISCA message because up to 112
peripheral devices and 5 controllers are
connected. Because of this, the peripheral
device's address of VISCA command is locked to
1 when using VISCA over IP. If the peripheral
device's address is set to other than 1 for the
VISCA command, the peripheral device works
without hindrance since the peripheral device
recognizes that its address is set to 1.
Peripheral device
Locking the controller's address of the VISCA
message to 0.
For the same reason as the peripheral device's
address, the controller's address of VISCA
command is locked to 0. If the controller's
address is set to other than 0, the peripheral
device works without hindrance, and the reply
address from the peripheral device is always set
to 0.
Prohibition of specifying the broadcast
address for the VISCA message
Do not use the broadcast address because it
requires the serial communication. Operations
under the broadcast address is set to the
command are not guaranteed.
Peripheral device
Prohibition of the Address Set for VISCA device
setting command
Do not use this command because it requires the
serial communication. Operations under the
Address Set command is sent are not
guaranteed.
VISCA Network Change command is not
supported
This cannot be issued because it requires the
serial communication.
Expiration time for an on status of the tally
lamp
The tally lamp is turned off if not receiving an ON
command from any controller for 15 seconds
after receiving an ON command of TALLY ON/
